Way out of time - took around half an hour after exploring blind alleys (2001/3 and 23x29 obviously weren't going anywhere, but 100+567 looked promising)

lmao reminds me of my sis on conundrums - always insists we pause it and then takes usually 10 minutes after asking "does it end in ER...etc" then when she finally gets it is really chuffed "I beat the contestants"
